machine cycle

Hello all,

the way we calculate 1 machine cycle period in 8051
clock = 12MHz
then 1m/c = 1/ (12MHz / 12) = 1 usec

In case of ARM7, I have peripheral clock for timer = 12Mhz (after doing all the calculations of PLL)
can you guide me the time period of 1 machine cycle in case of ARM7.
does it mean 1 m/c = (1/12Mhz) = 83 nsec

Please guide..

Thanks and regards.
